rn'rnnson, NEW Jnnsnr SlOP MOl'ION FOR MACHlNESFOR DOUBLlNG SILK AND OTHER FIBERS.

To all whom it may concern.-

Be it known that I, THOMAS S. MoELnosE,

Passaic and State of New Jersey, have inventeda new and useful Improvement in Stop- Motions for Machines for Doubling Silk and other Fibers, of which the followingis a speciilIy invention relates to doubling-machines in which the head of the spindle of the windingbobbin bears with its weight upon a drivingwheel, so vas to be rotated by frictional contact with said wheel by an automatic stop-motion upon the breaking or giving out of a strand, so as to stop the rotation of the bobbin.

The object of the invention is to obtain a more positive and prompt stoppage of the winding-bobbin in case of the breaking or giving out of the strands, or in case the bobbin becomes full. 7 p i In stop-motions of the kind above described wires or taller-wires. The drop-lever or faller is always so nicely balanced that the weight of a drop-wire falling on the lever or faller will cause it to tilt and aid in eifecting the raising of the winding-bobbin.

with a winding-bobbin or a spindle and a frictional engagement with thebobbin or its spindle-head of a slider-bar'having an'inclined or wedge-like upper surface foracting on the spindleto raise the bobbin, aspring for actuating the slider-bar to cause it to raise the spindle and bobbin, a catch for holding the or set, and drop-wires and a drop-lever, the latter of which is adapted to engage with said catch for releasing the slider-bar, all as more fully hereinafter described. The tilting of the tion to act on the catch and tobe acted on by atappet on the spindle or bobbin to raise the spindle and bobbin; and this'tappet, in conjunction with the aforesaid elements, constitutes a part ofmy invention. The above-described combination. serves only to raise the part of Letters Patent No, 289,117, dated November 2'7, 1883.

Application filed February 23, 1883. N0 model.)

winding-bobbin when a strand breaks or gives out; but my invention further consists in a novel combination of devices, whereby the bobbin or spindle will be raised out of contact with the driving-wheel when the bobbin is full, as hereinafter particularly described.

The invention also consists in'various details of construction and combinations of parts, hereinafter described, and pointed out in the claims. I

In the accompanying drawings, Figure 1 is vertical section of a portion of a machine embodying my invention. Figs. 2 and 3 are cor responding sectional views of a portion of the machine upon a larger scale, the former figure showing the bobbin-head in an operative position, and the latter figure showing it in an inoperative position; and Fig. 4 is a plan view of the parts shown in Figs. 2 and 3 and upon the same scale.

Similar letters of reference designate corresponding parts in all the figures.

A designates a 'portionof one of the end -frames of the machine, and A designates one upon a board, B, and are surmounted by fliers a. From these spools and fliers the strands b are carried over the tension-rods c, and through the drop or faller wires-d and traverse bar e, to the winding-bobbin G (Shown only in Fig. 1.) O is the spindle of the windingbobbin.- So far as described, the machine possesses no particular novelty, but 'is very commonly used for the purpose of doubling silk, and it is customary to place a row of winding-bobbins on each side of the machine.

D designates a shaft extending lengthwise of the machine and carrying wheels D, each ofwhich is adapted to impart motion to a winding-bobbin by frictional engagement with the spindle-head 0 upon the spindle 0.

E designates brackets or hangers, which ex tend from the rail A, and have formed in them open bearings f, wherein the spindle O of the winding-bobbin may turn. The spindle-head ()"rests with the weight due to the spindle and bobbin on the driving-wheel D,

.be raised to take its head out of contact with said driving-wheel.

' In each bracket or hanger E is arranged a slider-bar, F, which is provided with a horn or handle, F, whereby it may be drawn out ward; and G designates a catch, which is pivoted at g, and provided with a shoulder, g, for engaging with a pin, 9 on the sliderbar, for holding it in its outward position, as shown in Fig. 2.

In the upper surfaceof the slider-bar there is an incline or wedge, 71, which is formed by a depression in the'bar, and when the sliderbar is drawn out, so that the shoulder g of the catch G engages with the pin this hollow' or depression is opposite or below the spindle O, and the latter can drop so that its head 0 will rest upon the driving-wheel D. \Vhcn the slider-bar is moved inward into the position shown in Fig. 3, the inclined surface 7L thereof raises the spindle, so as to take its head 0 out of contact with the wheel D, and said spindle is supported. upon the upper surface of the slider-bar.

Connected with the inner end of the sliderbar F is a rod, i, which plays in a guide, 2", in the bracket E, and said rod is surrounded by a spiral spring, i which is compressed'as the slider-bar is pulled outward or set, and which exerts a constant tendency on said bar to move it inward. Consequently as soon as the catch g is raised out of engagement with the pin the slider-bar flies forward under the impulseof the spring 1 and raisesthe spindle head C out of contact with its driving-wheel D.

H H designate a drop-lever or faller, which is pivoted in a fulcrum-piece, I, secured to a rail, A. One arm, H, of this lever extends into proximity with the end of the catch G, as shown in Figs. 3 and 4, and the other arm, H, isinade of considerable width,,and extends under the drop-wires or faller-wires d, as shown in Fig. 4. \Vhen the drop or faller wires are all held up by the strands 6, as shownin Fig. 2, the arm H of the drop-lever or faller descends and rests upon the projecting portion j of the bracket E, as shown inFig. 2.. WVhen in this position, the slider-bar F is held outward by the shoulder g of the catchG, and the spindle-head O rests upon and is rotated by frictional contact with the driving-wheel D.

Upon the end of the spindle-head G" is a pin, 70, constituting a tappet, and when the end of the arm H of the lever or faller rests upon the support j, this tappet passes over itwithout interference as the spindle-head G rotates. Thedrop-lever or faller H H is so nicely balanced that if one of the strands b breaks or runs out and its drop-wire or fallerwire (2 falls onto the arm H, the lever is tilted and its arm H is raised into contact with the endof the catch G. The rising of the arm H.

might of itself serve to lift the catch" G if;

properly organized. In the present instance,

however, the end of the armH rises into contact with the end of the catch, and as the spindle-head G continues its rotation its tap- I pet k strikes against the under side of the arm H, and raises it and the catch Gsufficiently to move the shoulder out of engagement'with bar constitutes a lifter or lifting device for raising the spindle.

In some machines the silk or other material on the winding-bobbin rests upon the drivingwheel D, and in such machines the operationwould be the same, except that the bobbin, instead of the spindle-head, would be raised out of contact with the driving-wheel D by the lifting action of the slider-bar F.

Sofar as described the mechanism does not provide for raising the bobbin when it be-.

comes full, and I will now describe how this is effected.

J designates a rock-shaft fulcrumed OIj0ll1-- naled in the brackets hr hangers E, and provided with an upwardly-projecting arm, -J=, carrying a roller, J and also provideda'vith a horizontally-extending arm, J which has a.

projection, 1, extending under the drop-lever or faller, and a set-screw, m, in the end. The. set-screw m limits the downward movement of.

the arm J and consequently regulatesthe distance from the spindle O and bobbin thereon to which the roller J 2 can approach.

It is-obvious that a pressure upon the roller J 2 in a direction away from the spindle'G will raise the arm J i, and through the projection.

Z will lift the arm H of the drop-lever or faller against the catchG, so that at the neXt rotation of the spindle-h ead the tappet It will strike:

the said arm, and by raising it will release. the

slider-bar or lifter, and so stop the rotation'of the winding-bobbin.

The roller J -has-a cam-face, n, or a portion in making theroller, or secured by attaching.

theretoa piece of leather or other material; and the roller'is weighted or'loaded on one binC occupies, as shown in Fig. 1, and asthe material increases on the bobbin, and as soon.. as itisfull, the materialwill catch the roller' J and, rotating it in the direction ofthearrow, Fig.2, will draw its portion of greatest proj ection' or cam-face against the bobbin, and so force the arm J backwardor away fromthespindle-and lift the arm J to raise the drops levergorrfaller-arm H. As soonas theibobbina is removed and a new one inserted, the roller I 1 5 f-greatest projection, which may be produced 2s9,11v I v i 3 J and the rock-shaft J and arm J resume their normalposition. (Shown in Fig. 2.) The rock-shaft J, with its arms J J constitutes a lever carrying the roller J 5 It will be seen that by my invention I effect the stoppage of the winding-bobbin in a very positive manner and without any delay, and

7 my invention is therefore of great utility;
